YOU DO NOT NEED A REFRACTOMETER IN ORDER TO BREW KOMBUCHA HOWEVER IT IS A LOT OF FUN TO KEEP TRACK OF YOUR SUGAR LEVELS
A refractometer will allow you to monitor the sugar level of your Kombucha or any other liquid. It works based on the gravity of the liquid that is measured. You will be able to read the Brix level, one degree Brix is 1 gram of sucrose (sugar) in 100 grams of solution. Eg. If you have a Brix level of 4% in your kombucha that would mean that there is about 4g of sugar per 100ml.
Be aware that refractometers are not 100% accurate. The longer your kombucha ferments the less accurate they become because of all the good things that the bacteria and yeast produce. Even if all the sugar is already consumed it would never go down to 0%Brix, because of all the other minerals and acids that influence the gravity of the solution. Eg. I have never seen the Brix level go below 1.6%
I have to say it is quite fun to measure the sugar levels of all sort of things, like Kombucha, soda drinks, milk …
Especially useful if you need to control your sugar intake for dietary reason.
